Abstract: TAB TOP CAN OPENER             Abstract of the Disclosure A unitary opener device for tab-type cans, which is extremely inexpensive to fabricate, simple to use and reliable in operation.     A first embodiment comprises a unitary member having a handle portion adapted to be gripped by a user, and a working end portion having a pair of relatively inflexible nose portions, the nose portions being separated by a slot dimensioned to receive the exposed portion of the can opening tab. One of the nose portions has a shorter length than the other, while each of the nose portions is provided with an external convex fulcrum surface adapted to engage the can surface bearing the tab to assist in raising the exposed portion of the tab away from the can surface and rupturing the seal between the tab and the can surface.     A second embodiment comprises a unitary member having a handle portion adapted to be gripped by a user, and a working end portion having a single relatively inflexible nose portion dimensioned to be received in an aperture in the exposed portion of the can opening tab in frictional engagement therewith, so that insertion of the nose portion in-to the tab aperture, followed by rotation of the handle portion in a plane substantially perpendicular to the can surface, provides an opening force of sufficient magnitude to rupture the seal between the tab and the can surface.  The handle portion includes an inner surface with a portion adapted to contact the edge of the can after the seal has been ruptured, permitting the device to function as a handle for the can.

Abstract: Abstract of the Disclosure Disclosed is a method for production of briquettes from a polydispersed material, comprising the steps of push-ing of the polydispersed material through a briquette-forming channel and its simultaneous  pre-compression, followed by a final compression of the polydispersed material into a briquette. Said operations are carried out by means of a die in said channel, the pushing of the polydispersed ma-terial with its simultaneous pre-compression being perform-ed in at least one stroke of the die in the briquette-form-ing channel. In the course of all of the operations an adjustable side compression force is developed acting in a direction practically normal to the displacement of the polydispersed material in the briquette-forming channel, the adjustable side compression force being varied from a minimum value at which the pushing of the polydispersed material is accomplished along with its simultaneous pre-compression, to a maximum value at which the final compres-sion of the polydispersed material is performed.     A device for implementing the method for production of briquettes from a polydispersed material comprises a pressing head having a channel for forming briquettes and provided with a movable member contacting the polydisper-sed material displacing in the briquette-forming channel.          The movable member is coupled with a mechanism providing the displacement of the movable member in a direction sub-stantially normal to the displacement of the polydispersed material along the briquette-forming channel.  The device is also provided with a die kinematically coupled with a drive providing a reciprocating motion of the die so that is capable to enter the briquette-forming channel.  The me-chanism providing the displacement of the movable member has an eccentric shaft kinematically linked with the die drive and provided with a rod coupled with the movable member.

Abstract: MOUNTING SYSTEM FOR APPLYING FORCES               TO LOAD-SENSITIVE RESONATORS                       Abstract A mounting structure for double-bar resonators to ensure symmetrical loading of the resonator responsive to ex-ternal forces.  In one embodiment, the resonator is connected to a pair of mounting pads through compliant coupling members.  The coupling members allow longitudinal, force-induced displacements of the mounting pads to load the resonator while making the res-onator insensitive to spurious transverse displacements of the mounting pads.  In another embodiment, a force is applied to a load sensitive, double-bar resonator through a force-transmit-ting bar which is mounted on an elongated flexure hinge.  The hinge is compliant about an axis of rotation which is perpen-dicular to the longitudinal axis of the resonator so that the hinge attenuates any force component acting perpendicular to the longitudinal axis of the resonator which would otherwise non-symmetrically load the resonator.

Abstract: HIGH SPEED CHARACTER WRITER     Abstract of the Disclosure The character writer disclosed herein is of the calligraphic type in which a pen or stylus traces out each character, positioning of the pen within the character region being accomplished by a pair of servomechanisms responsive to control voltages to provide movement along transverse axes.  The pen and servomechanisms are themselves carried on a carriage which can be traversed along a platen.  Character writing while the carriage is moving is accomplished by generating, for each character, a voltage which is proportional to carriage displace-ment within a character region and is combined with at least one of the servomechanism control voltages thereby to create a moving frame of reference which is essentially independent of carriage velocity.

Abstract: Abstract A wall edge marking device for resilient floor coverings for aiding in cutting the floor covering to size.  The marking device has a relatively smooth base surface capable of sliding along the surface of a resilient floor covering which is laid out on a floor area and extends beyond the area to be covered and up a wall surface.  An upright surface extends in a plane substantially normal to that of the base surface. The upright surface is biased back on each side to form a pair of angular faces.  The apex of the angular faces contacts the wall and slides along the surface of the floor covering overlapping the wall.  The intersection of the base and upright surfaces is rounded and has an adjustable marker protruding therefrom.  The device slides along the floor, against the wall, where it will trace a mark on the floor covering.  This mark can be used as a cutting line for cutting the flooring for an accurate fit.  The mark is adjustable in the vertical plane, to compensate for various thicknesses of flooring

Abstract: ABSTRACT      A system for the remote visual inspection of a structure including two vessels, one disposed within the other and defining an annulus therebetween.  A guide member is provided circumferentially about an upper periphery of the two vessels.  Mounted on the guide member are two motor-driven, diametrically opposed trolleys which support a flexible track member which extends downwardly through the annulus from one of the trolleys and back up the other side of the annulus to the other trolley.  At least one motor-driven carriage is mounted on the track member and carries a camera and light source.  By appropriate positioning of the trolleys and the carriage, all the surfaces of the vessels defining the annulus are accessible for visual inspection by the camera.  In accordance with a particular preferred embodiment, markers are placed at preselected points in the annulus on one of the vessels to permit verification of the location of the camera and carriage.          Advantageously, the markers are in the form of a preselected pattern to provide verification of the clarity of the image being transmitted by the camera.  In accordance with another preferred embodiment, the system further includes means for recording signals received from the camera and simultaneously recording the position of the camera.

Abstract: ABSTRACT It had been observed that all of the commonly used types of dish drying racks do not provide satisfactory service. Two critical faults had been identified:    The water which drips from drying dishes remains in the pan underneath the rack and rotts. The two piece drying racks are also hard to clean, fact which is further worsened by many sharp edges and narrow passages commonly present on existing racks.            In this invention the dish drying rack is made from one piece, provides adequate slope of the bottom plate to allow for all water to drain out to the sink. Furhter, the design allows for easy cleaning by having all corners and edges rounded, and by providing sufficient space for a hand with a cleaning cloth.
